Exam 3 Flashcards
1
Q
Wound assessment
A
1) restrain horse
2) evaluate overall health
3) Assess type of wound
4) Assess age of wound
2
Q
Biosecurity
A
- series of management protocols to prevent or limit the spread of infectious diseases
- goal to prevent diseases from happening at all
3
Q
Why shoes?
A
1) protection or prevent excessive wear
- once young horses put in work, footing can wear hoof away
2) shoes increase traction on footing
- minimize slipping
- studs and caulks increase even more (cleats)
3) gait alteration
- heavier shoe to add animation (knee and hock action or flexion) during movement
4) therapeutic reasons
- therapeutic shoes correct foot alignment and other problems (wedge pad or shoe with a wing)
4
Q
Rasping the hoof
A
- filing down the hoof wall and sole
- always use a 45 degree angle or heel to toe across foot rather than a perpendicular (side to side motion) because it can create uneven dips
5
Q
Woven Wire
A
Pros: 1) durable if installed well and maintained 2) low to moderately expensive 3) sight board on top Cons: 1) horses feet can get caught
6
Q
Tracking
A
- 4th part of lameness evaluation
- track horse at walk and trot both straight away and in circles to look for gait deviations
- if predicts its due to soft tissue injury they may track horse on soft footing
- if predicts its due to bone or joint issues should be monitored on hard footing such as asphalt
7
Q
MRI
A
- very advanced, give clearer image of tissue changes, tendon problems
- very expensive
8
Q
Equine Infectious Anemia (EIA)
- 1888
A
- virus that can affect all equines (specific pathogen)
1) Testing - Leroy Coggins - 1970s (Coggins Test)
- Govt program for surveillance and eradication
2) Transmission - infected horses (blood biting insects, dirty needles or bits, infected blood)
3) Clinical Signs - 2 weeks to several months of high fever, depression, lack of appetite, rapid loss of body condition
4) Vaccine/Treatment - none
5) Management - test every 12 months
9
Q
Tetanus
A
- caused by clostridium tetani, in places that harbor anaerobic bacteria (rust), spore forming bacterium
1) Transmission - not contagious, infection through punctures, lacerations, exposed tissue
2) Clinical Signs - muscle stiffness, rigidity, flared nostrils, hypersensitivity
3) treatment - supportive
4) management - vaccinate annually, can give tetanus antitoxin after suspected exposure
10
Q
Blood flow to hoof
A
- venous blood returned via pumping action
1) venous plexus on both sides of lateral cartilages - coffin bone pushes blood back to heart
2) movement - weight bearing constrict veins and pushes blood out
- swing phase opens vessels (arterial pressure and gravity bring blood in)
11
Q
Nerve blocking
A

2) hind hooves faster than front (12%)
3) fastest in spring
4) slowest in winter
5) biotin (vitamin B) increases rate of growth
- helps horses with poor hoof growth or hair benefit from it in their feed
14
Q
Using the knife for farrier work
A
- be careful to not take off too much sole bc if it’s too thin bruising will occur
- and don’t take too much of the frog off bc if it is not big enough there will be a lack of pressure with the ground and will compromise blood flow/return and it will increase chances for contraction of heels
- leave the hoof knife to the pros
15
Q
1) Antibiotic
2) Antiseptic
3) Antimicrobial
4) Antibacterial
A
1) drug that kills or slows growth of bacteria
